REPRODUCTION OF IMAGES ON GLAS3, PORCELAIN. CERAMIC, METALLIC, OFF OTHERSUB-FACES.

N 0 Drawing.

T 0 all who'mdt may concern:

Be it known that I, Haoincn Ax'rmis, of 3 Fitzroy street. Oxford Street,London. England, artist, have invented certain new and usefullmproreuwnts in or Relating to the lh-produetimi of imageso1i-tllass,ioreelain. Ceramic. Metallic. or other Surfaces.

v of water. about 2 parts by weight of honey or other solubleearlmhydrate. and about eighty parts by weight of a solution ofnitrocellulose miscible with water, for example. a mixture of alehoholor metlrvlated spirit (denatured alcohol) and eollodiolu Potassiumbieln'onmte is practically insoluble in the mixture and is not includedin the pres ent invention. 'lhe proportions indicated are of essentialimportance. Instead of al- ('oltol another liquid capable of renderingthe collodion miscible with water may be em ployed.

By the combination of the substances above mentioned in the proportionsstated, a singlev solution is obtained of ample sen-- sitizing power.whereby the most artistic subjects can be. reproduced in any dimensionswithout. transfer. and with little requirement for operative shill.

Example: 40 parts by weight eollodion solution (composed of 18?) partsby weight of other. 202 parts by weight methylated spirit or alcohol andlparts by weight of gun-cotton). l0 parts by weight of methylatedspirit. 1 part by weight of ammonium or sodium bichron'mte. 2 parts byweight. of honey or other soluble carbohydrate. The powdered biehromateand the honey are dissolved in about two and a half parts by weight ofwater. the spirit is added, and then the eollodion solution. I do notconfine myself to this particular solution, the; ingredients of-whichmay be varied within the Specification of Letters Patent.

range above indicated, and the proportioiis also may be altered withincertain limits.

By sensitizing the desi1'ed surfaee with this solution and exposing itunder a transparency. the latent image obtained will take up thepowdered pigment or color perfectly, and reproduce every detail andshade of the transparency. l have further found that when the surfacethus treated with color is washed with water. the carbohydrate andbichromate are at once entirely removed without in any way displacingthe pigment, which retained on the surface by the. uniformly distributedcollodion. The surface can then he at once tired to fix the pigment. Adirect remroduction of the original image may thus be obtained on thedesired surface. In reproducingimages with the solution I proceed asfollows :-The glass, porcelain, enameled metal, or other surface toreceive the impression is coated with an even film of the sensitizingsolution and dried. preferably by a gentle heat until the surface ceasesto be adhesive to an object placed in contact with it. The image ordesign is then placed in contact with the sensitized surface and exposedso that all light striking the latter first passes through the design.this is not sufficiently transparent as for example in the ease of anengraving on paper, it-

should be rendered so by treatmept wiitli a substance such as benzenefor example. T he length of the exposure depends on the intensity of thelight and the density of the original design. After the exposure thesurface may be gently warmed for a few minates, and a suitable pigmentor color is then dusted on and may be rubbed in with a brush. The powderwill adhere to the film inversely as the action of the light has takenplace. Thus it will attach itself to those portions of the surfacecorresponding to the dark portions of the original. The surface is thenwashed with water, whereby the soluble matters in the film are dissolvedand removed, leaving the image in pigment or color thereon. The surfaceis then dried- .wise as above explained.

to first make a permanent transparent model of the required design'asexplained later.

In the tiring, the collodion film left on the surface after washin isdissipated without disturbing the image and leaves no residue.

The pigment or coloring matter will vary according to the natureot'ithiz substance on which the copy is to be made.

ployed in glassstaining; for pottery, cerainie paint or pigments; forenameled metals, enamel powders.

I prefer, as before mentioned, to prepare what 1 style a model of theimage or design to be reproduced For this purpose I produce a replica ofthe desired design, in the manner hereinbcfore explained, upon a sheetof glass or like transparent material. The replica may be protecteditdesired. This replica serves as a permanent model, convenient tohandle and from which any de-,

nary lampblack for example may be used for this purpose, being taken upperfectly by the exposed surface; it. is however dillicult to retouchit.

The solution may be applied for the reproduction of in'iagcs on wood,metallic or other surfaces in cases where it is not desired to fix theimage by tiring. In such cases when the surface is porous it should beenameled or coated with a suitable ground Thus for glass 1 may employcolors such as are em- 3 weight of sensitizing bichromate, 2.5 parts byweight of water, 2 parts by weight of a soluble carbohydrate, and 80parts by weight of a solution of nitrocellulose miscible with the waterpresent.

2. For the reproduction of images upon glass, ceramic metallic and othersurfaces, a sensitizing solution consisting of 1 part by weight ofammonium bichromate, 2.5 parts by weight of water, 2 parts by weight; ofa soluble carbohydrate, and 80 parts by weight of a solution ofnitrocellulose miscible. with the water present.

For the reproduction of images upon glass, ceramic, metallic and othersurfaces, :1 sensitizing solution consisting of 1 part by weightof'sensitizing bichromatc, 2.5 parts by weight of water, 2 parts byweight of a soluble carbohydrate,and 50 parts by weight, of a mixture ofcollodion and alcohol.

i. For the reproduction of images upon glass. ceramic metallic and othersurfaces, a sensitizing solution consisting of one part by weight ofammonium bichromate, 2.5 parts by weight of water, 2 parts by weightot asoluble carbohydrate, and parts by weight of a mixture of collodion andalcohol.

In witness whereof, I have hereunto signed my name in the presence oftwo subscribing witnesses.
